Primary spinal cord lymphomas are rare, and are either extra-/intradural masses with leptomeningeal infiltration or intramedullary in nature. The authors present a patient with a diffuse large B-cell lymphoma involving the sacral nerve root, extension to extradural space, and the cranial nerve.

Object : We intended to investigate the relationship between the degree of injury on MRI and the outcome of the patients with diffuse axonal inury. Method : From january, 1995 to march, 1999, 22 patients were supposed to have diffuse axonal injuries by means of their neurologic signs and MRI. We investigated their prognosis according to CT, MRI and initial neurologic findings. Result : 1) The lesions were mainly located at white matter of cerebrum, corpus callosum, brainstem, and basal ganglia. 2) The lesions of white matter were most commonly in the frontal lobe and temporal lobe. 3) The majority of corpus callosal lesions were located in the posterior body and splenium, but anterior corpus callosal lesions combined with posterior lesions were not found. 4) Brainstem lesions, all non-hemorrhagic, were mostly located in the dorsolateral aspect, not be found on CT. 5) The brainstem lesions were found in 10 cases among total 22 cases, and corpus callosal lesions were accompanied with 8 cases of brainstem lesions. 6) The patients with brainstem lesions had worse prognosis. Conclusion : It is important and reasonable to take brain MRI to identify the brainstem lesions in any cases of suspicious diffuse axonal injury, and we should remind that the diffuse axonal injury with stem lesion has worse prognosis.

Primary diffuse large B-cell lymphoma of the seminal vesicle is an extremely rare disorder, with only two cases reported in the English literature. Here, we present imaging findings of a case of primary diffuse large B-cell lymphoma of the seminal vesicle. On transrectal ultrasonography, the mass presented as a 3.0-cm-sized heterogeneous, hypoechoic lesion in the right seminal vesicle. Computed tomography (CT) revealed a mass with rim-like enhancement in the right seminal vesicle. On magnetic resonance imaging (MRI), the tumor showed iso-signal intensity on T1-weighted images and heterogeneously intermediate-high signal intensity on T2-weighted images. The tumor showed rim-like and progressive enhancement with non-enhancing portion on dynamic scanning. Diffusion restriction was observed in the mass. On fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET/CT) imaging, a high standardized uptake value (maxSUV, 23.5) by the tumor was noted exclusively in the right seminal vesicle.

Pigmented villonodular synovitis (PVNS) is a rare proliferative disease involving the synovial membranes. Complete excision with a total synovectomy is important for diffuse type PVNS because of its high recurrence rate. In the ankle, complete excision of diffuse type PVNS is difficult due to the anatomical structure of the ankle joint. This paper reports the author's experience of surgical treatment with combined open and arthroscopic synovectomy. In this manner, it is expected that the complications of the open procedure and the recurrence rate of arthroscopic procedure can be reduced.

A characteristic imaging finding in cases of methanol intoxication is putaminal necrosis, but its presence is usually not suspected due to its rarity. Methanol intoxication generally produces serious neurological symptoms that include visual disturbances and diminished consciousness, characteristically with metabolic acidosis. We reported the case of a 59-year-old man who was admitted to the hospital with diminished consciousness. Acute methanol intoxication was determined as the cause. Laboratory tests revealed high anion gap metabolic acidosis. Diffusion-weighted MRI indicated diffuse symmetric diffusion restriction lesions in the subcortical white matter of both cerebral hemispheres.

Pigmented villonodular synovitis (PVNS) is a rare proliferative disease involving synovial membranes. Natural history and etiology of PVNS are not well known. PVNS presents as localized or diffuse tumor like nodular lesion of the synovial lining of the joint and the synovial spaces adjacent to the joints. Though histologically benign, it is a very aggressive lesion, capable of bone destruction and widespread infiltration of surrounding tissues. Standard therapy is surgical resection, but due to the infiltrative growth, the recurrence rate is significantly high. After several relapses surgical treatment of diffuse PVNS becomes difficult and may require amputation of the involved limb. Radiotherapy can provide an effective treatment option for patients with large lesions or lesions which are not suitable for surgery, after incomplete resection to prevent relapses or to avoid amputation. We report 2 cases of diffuse PVNS in the knee joint treated with arthroscopic gross total synovectomy and radiotherapy.

The introduction of high-resolution CT (HRCT) in recent years has improved the ability of radiologists to detect and characterize the diffuse infiltrative lung disease (DILD). The detection and diagnosis of diffuse lung disease using HRCT are based on the recognition of specific abnormal findings. In this article, pattern recognition of HRCT findings is reviewed in the differential diagnosis of diffuse infiltrative lung disease. In general, HRCT findings of lung disease can be classified into four categories based on their appearances. These categories consist of (1) nodules and nodular opacities, (2) linear and reticular opacities, (3) increased lung opacity, and (4) decreased lung opacity, including cystic lesions.

Diffuse sclerosing papillary carcinoma(DSPC), a variant of papillary carcinoma of the thyroid, is characterized by diffuse involvement of one or both thyroid lobes, and histologic features such as prominent sclerosis, intense lymphocytic infiltrate, numerous psammoma bodies, and squamous metaplasia together with the characteristic cytoarchitectural pattern of classical papillary carcinoma. We experienced a case of fine needle aspiration cytologic(FNAC) findings of DSPC, which was confirmed by histologic examination of the thyroidectomy specimens. The patient was 26 years old female who presented with diffuse firm enlargement of the thyroid gland with enlargement of many cervical lymph nodes. FNAC smears showed numerous psammoma bodies, many lymphocytes, metaplastic squamous cells, absence of stringy colloid, and epithelial cells showing classical features of papillary carcinoma, such as nuclear grooves, intranuclear unclusions, and ground glass chromatin pattern.

Diffuse alveolar hemorrhage (DAH) is a life-threatening and medical emergency that can be caused by numerous disorders and presents with hemoptysis, anemia, and diffuse alveolar infiltrates. Early bronchoscopy with bronchoalveolar lavage is usually required to confirm the diagnosis and rule out infection. Most cases of DAH are caused by capillaritis associated with systemic autoimmune diseases such as anti-neutrophil cytoplasmic antibody-associated vasculitis, anti-glomerular basement membrane disease, and systemic lupus erythematosus, but DAH may also result from coagulation disorders, drugs, inhaled toxins, or transplantation. The diagnosis of DAH relies on clinical suspicion combined with laboratory, radiologic, and pathologic findings. Early recognition is crucial, because prompt diagnosis and treatment is necessary for survival. Corticosteroids and immunosuppressive agents remain the gold standard. In patients with DAH, biopsy of involved sites can help to identify the cause and to direct therapy. This article aims to provide a general review of the causes and clinical presentation of DAH and to recommend a diagnostic approach and a management plan for the most common causes.
